To all whom it may concern:

Be it known that I, J ULES ALPHONSE DEISS, a citizen of the Republic ofFrance, residing at Marseilles, in the said Republic, have inventedcertain new and useful Improvements in Presses, (patented in FranceApril 20, 1891, No. 212,897; in Belgium October 17, 1891, No. 96,822; inEngland October19, 1891,No.17,886; in Spain October 16,1891, No.12,611;in Porro tugal January 17, 1892, No.1,647; in Tunis December 12, 1891,No. 43; in Austria-Hungary December 3, 1891, 'No. 31,025 and No. 53,680;in Turkey July 23, 1891, No. 235, and in Italy Septemberv 30, 1891, Vol.XXV, No.

1 30,218,) of which the following is a specification.

I have invented this system of press which is based on the use of amovable compressor or metallic cylinder of which the construction willbe shown farther on. The metallic sides offering a considerableresistance, a very energetic pressure can be exercised, from which itfollows that the results are greater than it bags are used. Moreover thecakes obtained are always alike and present an evenness of cohesionthrough the entire mass, which has been subjected to an absolutelyuniform compression.

In order to make my invention more clearly o understood I have shown inthe accompanying drawings the means for carrying the same into practicaleifect.

In said drawings Figures 1 and 2 show in detail the filtering surface ofthe inner sides 5 of the press box. Fig. 3 is a horizontal view of thepress box. Fig. 4, is a vertical section of the same. Figs. 5, 6, and 7show the arrangement of the press box on the hydraulic press and on thetransfer car.

0 The press box is essentially formed by a cast or other metalliccylinder F presenting at its inner part a rectangular section with cutangles or any other appropriate section. The vertical sides, suitablyplaned, are provided 5 with longitudinal grooves or holes which serve tolodge the movable tubes 0 whose surface toward the interior of thecylinder is provided with parallel saw cuts .9 8, arrangedperpendovetailed end cl at the bottom to facilitate their putting inplace, is placed a series of adjoining metallic wires f, which stretchedon thesaid tubes constitute a surface which only under strong pressureallows the liquid pressed from the cellnles of the matter undertreatment to escape. This liquid penetrates into theinterior of thetubes by the saw cuts of which I spoke above, and escapes at the base ofthe press box at the ends of the tubesinto a gutter or basin arrangedfor this purpose.

According to the nature of the matters to be treated in the press box afiltering tissue is or is not inserted between the stretched wires andthe outer side of the vertical flowoff canals. These can have a squaresectional form as shownin Fig.2 but theycan be given any other form.

The inner sides of the press box are directly in contact with thecompressed matters and present a mixed surface composed of smooth fullparts and permeable parts formed by the juxtaposed wires. These wirescan have a circular, triangular, square, trapezoidal or any 7 othersection. Their spacing can vary. They have the function of letting onlythe liquids pass and of retaining the entirety of the solid bodies. Itis to assure a considerable resistance at the permeable surface whichtheyform, So that the wires are arranged over the very solid canals ortubes giving them an indeformable supporting base, leaving at the sametime outlet passages for the expressed liquid. This supporting base isformed by the tube, which could be replaced bya solid surface. As soonas the extracted liquid passes to the interior of the canals, it flowsoff immediately at the base, as specified above.

Each completed press-box is or may be 0 mounted upon wheels so as tofacilitate handling and moving of the same. I contemplate employingpress-boxes of this description in connection with special means forcharging and discharging the same, but as these form 5 no part of thepresent invention, and as any ordinary or suitable means for thispurpose maybe employed it will not be necessary here to describe them.

For compressing the oleaginous seeds or other matters in the cylindricalpress-box any powerful compressing device may be used, such as ahydraulic press, a common form of which is shown in Figs. 5 and 6 and towhich the press box is conveyed upon a suitable car or truck as shown inFig. 7.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The herein described press-box comprising a receptacle or chamberhaving in its inner wall channels or passages communicating with thechamber by transverse slots or openings, and a series of wires extendinglengthwise of said canals or passages and covering the slots oropenings, substantially as described.

2. The combination with the wall of'the press box having interiorpassages or canals communicating by a series of openings with theinterior of the press-box, of parallel wires covering said openings,substantially as described.

3. The combination with the wall of the press-box having longitudinalgrooves, of
